PILL-MACHINE.

SPECIFICATION forming part of Letters Patent No. 332,493, dated December15, 1885.

Application filed February .10, 1885.

To all whom it may concern:

Be it known that I, ERsKINE A. OoLEs, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and use ful Improvement in Pill-Machines, whichimprovement is fully set forth in the following specification andaccompanying drawings, in which Figure l is a partial vertical sectionand partial side elevation of a pill-machine embodying my invention.Fig. 2 is a side elevation at a right angle to Fig. 1. Figs. 3 and 4 areviews of detached portions.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention consists of a pill-machine ha ing a two-part cam adaptedfor causing the operation of both dies thereof, whereby a pill may becompressed and ejected or removed.

It also consists of means for rendering the dies adjustable.

It also consists of means for rendering the lower die removable.

Referring to the drawings, A represents the frame of the machine, and BB bosses thereof. In the boss B is fitted a head or socket, O, forholding one of the dies, D, of the machine. In the boss B is fitted ahead or socket, G, for holding the other die, D, of the machine, each(lie having on its workingface a depression corresponding to the shapeof half of a pill to be made. The dies of the sockets O O are secured tosaid sockets by a set-screw or pin, a, and screw-stud or pin a,respectively, as shown in Fig. 1. At the upper or outer end of the bossB is supported a bed, E, which has an opening for the passage of the endof the die D and receives the end of the die D when the dies are closed.In the end of the socket G opposite to the die D is fitted a screw-bolt,F, and connected with the end of the socket O opposite to the die D, bya pivotal or hinged joint, is a screw, G, which latter is passer]through one limb of an elbowlever, H, and attached thereto by nuts G,the other end of the lever being adapted to be engaged by a-cam-lever,J, which is pivoted to the upper part of the frame A, and also adaptedto engage with the head of the bolt (No model.)

F, it being seen that the elbow-lever H is pivoted to the frame A andhas bearing against it a spring, K, which, secured to the frame, servesto restore said lever, with connected parts, to its normal position. Theexterior surface of the socket G is formed with a groove, d, into whichprojects a pin, stud, or screw, L,connected with the boss B, for guidingsaid socket, and consequently the die' D, in a true and steady manner.The bed E is securely held by a screw or bolt, M, and the bolt F hasfitted to it a jam-nut, F, for holding the same in adjusted position, itbeing evident that by means of the bolt F and the nuts G the dies may beadjusted relatively to each other with nieety and for purposes of theformation of pills of different sizes. The cam-lever J has two swells,JJ, the swell J being adapt ed to bear against the head of the bolt F,for depressing the same and advancing the die D. The swell J is adaptedto bear against the adjacent end of the lever H, and thereby raise thedie D. The dies are shown closed. When the cam lever J is raised, theswell J leaves the head of the bolt F, so that the socket C, underaction of the spring B, is raised, thus raising the upper die. The swellJ then comes in contact with the head of the elbowlever H, whereby thelower die is raised, and its working-face appears above the bed E. Thecam-lever Jis now partly lowered,so that the swell Jclears the lever H,and the spring K restores said lever to its normal position, thuslowering the die D and placing its working-face below the bed E. Thematerial of which the pill is to be made is now placed in to thedepression at the top of the lower die,

and the cam-lever is lowered to a greater extent, so that the swell Jagain bears against the bolt F, thuslowering the upper die,whereby thematerial between the dies is compressed and formed into a pill. Thecam-lever is again raised, and thus the dies first separate or open, andthe lower die is raised, whereby the pill is ejected above the bed, andmay be removed by sweeping or direct application of the fingers of theoperator.

In order to remove the lower die,the nuts G G are slackened, and as thescrew G is passed through an open slot in the end of the limb of 109 thearm H and has a pivotal connection with the socket C, it may be swungoutwardly clear of said limb, whereby the socket and its connected diemay be lowered from the boss B and entirely removed therefrom. The studa is then loosened, and the die may be readily disconnected from thesocket and substituted by a different die, or replaced,as desired. Theupper die may be removed by loosening the screw a.

In orderto adapt the machine for the formation of pills of differentsizes, the sockets C 0' are provided with dies D I), the workingfaceswhereof are of different sizes. The bed E has a number of openingscoincident with the dies D D, so that the latter may enter saidopenings. On the top of the boss B is a feed-box, N, which is secured toa holder, P, the latter being pivoted to the boss, and provided with aproper handle, whereby the feed-box may be swung laterally, clear thedies DD, and returned over the bed E. An opening, Q, is made in thebottom of the feed-box, and the box is rotatable on its holder, so thatsaid opening Q may be located to register with either of the openings inthe bed E, the side or rim of the holder being expansible, so that thebox may be liberated, and when the box is restored and adjustedrelatively to the opening Q and openings in the bed E said side or rimis tightened by means of a screw, R, thus clamping the box in position.A screw, S, in fitted to the boss B, in order to limit the return motionof the holder P and adjust the opening Q with precision relatively tothe opening in the bed.

When pills of a determined size are to be made, the feed-box is adjustedso that the opening Q registers with the opening in the bed, whichconforms to said size. The box is moved over the bed so that thematerial therein falls through the opening Q into the proper opening ofthe bed, and thus the latter opening is filled. The box is then movedclear of the path of motion of the dies, after which the lever J isoperated similar to that hereinbefore described, whereby the material iscompressed and the pill made, and then raised above the bed, aspreviously stated, it being noticed that the other openings in the beddo not register with the opening Q in the box, and are thus not suppliedwith material, and

consequently no .pills are formed therein; but

of the cam being directly in contact with the head of the socket orholder of the die D, substantially as and for the purpose set forth.

2. A two-part cam and an elbow-lever, in combination with the dies andtheir sockets or holders, the socket of the upper die having anadjusting screw-bolt,against which the cam operates,substantially asdescribed.

3. In a pill-machine, the operating-lever J, having cams J and J, incombination with socket 0, provided with screw-bolt F, and having die D,and elbow-lever H, having socket C, carrying die D, pivotally securedthereto by the screw G, substantially as and for the purpose described.

4. The grooved socket O, carrying the die D, and pivotally hinged by thescrew G to the elbow-lever H, in combination with the boss B of theframe A and screw L, substantially as and for the purpose described.

7 5. In a pill-machine, a die pivotally connected with a screw-bolt anddetachably connected with an operating-lever, whereby said die may beremoved from its boss or guide, substantially as and for the purposeset'forth.

6. In a pill-machine, a die having a screw, G, pivotally connectedtherewith, in combination with an elbow-lever having a slotted limb andthe nuts G G, substantially as and for the purpose set forth. v

7. A machine with two or more dies of different sizes, a bed havingopenings registering with said dies, and a feed-box having adischarge-opening which may be set to either -of the openings of saidbed, substantiallyas and for the purpose set forth.

8. The dies and bed, in combination with a feed-box having adischarge-opening and a holder in which said box is adjustably held,substantially as and for the purpose set forth.
